Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149748, here are decompositions:

  • 17 + 149731 = 149748
  • 19 + 149729 = 149748
  • 31 + 149717 = 149748
  • 37 + 149711 = 149748
  • 59 + 149689 = 149748
  • 197 + 149551 = 149748
  • 227 + 149521 = 149748
  • 229 + 149519 = 149748

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 149,748 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
